The polar bear planet is diminishing. Since it's been estimated that by the middle of this century we'll no more have year-long Arctic sea ice, the polar bear could vanish in the wilderness.
Polar bears hunt seals by awaiting seals to come through holes in the ice. Additionally, they stalk their prey using their white camouflage skills from the mounds of sea ice. Get to know more about polar bear protection via https://polarsociety.com/.

Occasionally polar bears are known to creep on their bellies until they are near enough to hurry their prey, especially if no cover is available. Apart from seals, polar bears will consume Arctic foxes, birds, baby walruses as well as man if they're incredibly hungry.
Leading scientists think that the rapid pace of climate change (global warming) underway in the Arctic will create reverberating outcomes. Along with anticipated changes in ocean and atmospheric flow patterns, influence on the polar bear is very likely to become immediate and may be observed at a reduction of the burden of polar bears and in the birth and survival rate of their cubs.
Exceedingly vulnerable to disturbances, oil mining affects the polar bear in lots of ways. For example, when petroleum mining equipment drives too near the dens, it sends shock waves through the floor as it hunts for gas and oil reserves. It makes the polar bear mother; abandon her cubs, interrupting her searching routines. Considering that the Cubs don't leave the room until they're 3 weeks old when left, they will perish.
The combo of pollution moving into the North from roots thousands of kilometers apart, together with oil growth and global warming, could influence not just the polar bear world but also the whole ecosystem.
